Failure to followthese instructions could result in property damage, bodily injury or even death. Contact your local building or fire officials to obtain a permit andinformation on any installation requirements and inspection require-ments in your area.

P/N 775,024M Rev. C, 12/03

IMPORTANT WARNINGS CAUTION: Read this manual thoroughly before starting installation. For your safety, follow the installation, op-eration and maintenance instructions exactly without deviation. Failure to follow these instructions may result in a possible fire hazard and will void the warranty. If this appliance is not properly installed, a house fire may result. Contact local building or fire officials about requirements and installation inspection in your area.

1. DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE CONNECTED TO ANOTHER APPLIANCE.

2. Do not connect this appliance to air ducts or any air distribution system.

3. Do not install a flue damper in the exhaust vent-ing system of this appliance.

4. Do not use class B venting intended for gas appli-ances as a chimney or connector pipe on a pellet-fired appliance.

5. The minimum clearances must be maintained for all combustible surfaces and materials including; furniture, carpet, drapes, clothing, wood, papers, etc. Do not store firewood within this clearance space.

6. INSTALLATION DISCLAIMER - This stoves ex-haust system works with negative combustion chamber pressure and a slightly positive chim-ney pressure. Therefore, it is imperative that the exhaust system is gas tight and installed cor-rectly. Since Lennox Hearth Products has no control over the installation of your stove, Len-nox Hearth Products grants no warranty, implied or stated for the installation or maintenance of your stove, and assumes no responsibility for any consequential damage(s).

7. Burning any kind of fuel consumes oxygen. If out-side air is not ducted to the appliance, ensure that there is an adequate source of fresh air available to the room where the appliance is installed.

8. The stove will not operate using natural draft, nor without a power source for the blower and fuel feeding systems.

9. Never use gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid, or similar liquids to start or "freshen up" a fire in this heater. Keep all such liquids well away from the heater while it is in use.

10. CONTINUOUS OPERATION: When operated cor-rectly, this appliance cannot be overfired. Con-tinuous operation at a maximum burn can, how-ever, shorten the life of the electrical components (blowers, motors, and electronic controls), and is not recommended. Typical approved operation would include running at the low to mid range set-ting with occasional running on the maximum set-ting during the coldest periods of the winter. The blower speed control should be turned to high when operating the stove on the high heat setting.

11. CAUTION: NEVER PUT FINGERS NEAR AUGER. Pellet fuel is fed to the UltraGrate by a screw au-ger. This auger is driven by a high torque motor. The auger is capable of doing serious harm to fin-

gers. Keep pellets in the hopper at all times and keep fingers away from auger. The auger can start and stop automatically at any time while the stove is running.

12. CAUTION: HOT WHILE IN OPERATION. An appli-ance hot enough to warm your home can severely burn anyone touching it. Keep children, clothing and furniture away. Contact may cause skin burns. Do not let children touch the appliance. Train them to stay a safe distance from the unit.

13. APPROVED FUEL: This appliance is designed spe-cifically for use only with pelletized wood fuels only. With its advanced UltraGrate technology, this appliance is designed and approved for the burning of wood residue pellets with up to 3% ash content. This appliance is NOT approved to burn cardboard, nut hulls, cherry pits, corn, etc. regard-less if it is in pellet form. Failure to comply with this restriction will void all warranties and the safety listing of the stove. Consult with your authorized Lennox Hearth Products dealer for more informa-tion on approved pellet fuels.

14. FLY ASH BUILD-UP: For all wood pellet fuel-burning heaters, the combustion gases will contain small particles of fly ash. This will vary due to the ash content of the fuel being burned. Over time, the fly ash will collect in the exhaust venting sys-tem and restrict the flow of the flue gases. The ex-haust venting system should be inspected regu-larly and cleaned as necessary.

15. SOOT FORMATION Incomplete combustion, such as occurs during startup, shutdown, or incorrect operation of the room heater will lead to some soot formation which will collect in the exhaust venting system. A precautionary inspection on a regular basis is advisable to determine the necessity of cleaning. The exhaust venting system should be inspected regularly and cleaned as necessary.

16. DISPOSING OF ASHES: Any ashes removed from the pellet stove must be deposited in a metal con-tainer with a tight-fitting lid. The closed container of ashes should be placed on a noncombustible floor or on the ground, well away from all combus-tible materials, outside of the dwelling pending fi-nal disposal. If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be retained in the closed container until all cinders have been thoroughly cooled.

PLANNING YOUR INSTALLATION

QUESTIONS TO ASK LOCAL BUILDING OFFICIAL A correct installation is critical and imperative for reduc-ing fire hazards and perilous conditions that can arise when wood pellet burning appliances are improperly installed. The installer must follow all of the manufac-turers’ instructions. The installation of this appliance must conform to local codes and applicable state and federal requirements. Familiarity with these requirements before installation is essential. Important considerations to discuss with local building officials include: 1. Applicable codes (i.e. Uniform Mechanical Code,

State or Regional Codes.)?

Electrical codes: In USA, NEC, ANSI / NFPA 70-2002. In Canada, CSA C22.1 Power Supply Requirements – The power cord

must be plugged into a standard, 115 volt, 60 Hz grounded electrical outlet. The approximate power requirement is 250 watts. The power sup-ply cord must be routed to avoid contact with any of the hot or sharp exterior surface areas of the stove. When installed in a manufactured (mobile) home appliance must be electrically grounded to the steel chassis (see pages 6 and 7, Manufac-tured (Mobile) Home Requirements for additional requirements). These requirements must be met unless otherwise specified by state or local au-thorities.

WARNING: ELECTRICAL GROUNDING IN-STRUCTIONS: THIS APPLIANCE IS EQUIPPED WITH A THREE-PRONG (GROUNDING) PLUG FOR YOUR PROTEC-TION AGAINST SHOCK HAZARD AND SHOULD BE PLUGGED DIRECTLY INTO A PROPERLY GROUNDED THREE-PRONG RE-CEPTACLE. DO NOT CUT OR REMOVE THE GROUNDING PRONG FROM THIS PLUG. DO NOT ROUTE POWER CORD UNDER OR IN FRONT OF APPLIANCE.

2. Local amendments? 3. Is a permit required - cost? You may wish to contact your insurance company

to ask if they require this. 4. Is outside combustion air required? 5. Rooms where the installation is not allowed?

INSTALLATION / MAINTENANCE STANDARDS National Fire Protection Association – The primary NFPA standard that refers to installation and mainte-nance of pellet appliances and venting is NFPA 211: Chimneys, Fireplaces, Vents, and Solid Fuel appli-ances, Latest Edition. SELECTING A LOCATION The design of your home and where you place your stove will determine its value as a source of heat. A wood stove depends primarily on air circulation (con-vection) to disperse its heat, and therefore, a central location is often best. There are other practical consid-erations, which must be considered before a final selec-tion of locations is made. ♦ Existing Chimneys ♦ Pellet Fuel Storage ♦ Aesthetic Considerations ♦ Roof Design (rafter locations & roof pitch) ♦ Room Traffic ♦ Proximity to Combustibles ♦ Electrical Wiring The installation of this stove will require some research. Once your options are determined, consult with your local building department who will be able to give you the necessary installation requirements for your area (Is a building permit required?, Rooms where installation may not be allowed?, etc.). WARNING: CHECK ALL LOCAL BUILDING AND SAFETY CODES BEFORE INSTALLATION. THE IN-STALLATION INSTRUCTIONS AND APPROPRIATE CODE REQUIREMENTS MUST BE FOLLOWED EX-ACTLY AND WITHOUT COMPROMISE. ALTERA-TIONS TO THE STOVE ARE NOT ALLOWED. DO NOT CONNECT THE STOVE TO A CHIMNEY SYS-TEM SERVING ANOTHER STOVE, APPLIANCE, OR ANY AIR DISTRIBUTION DUCT. FAILURE TO FOL-LOW THESE INSTRUCTIONS WILL VOID THE MANUFACTURERS WARRANTY. SMOKE DETECTORS Since there are always several potential sources of fire in any home, we recommend installing smoke detec-tors. If possible, install the smoke detector in a hallway adjacent to the room (to reduce the possibility of occa-sional false activation from the heat produced by the stove). If your local code requires a smoke detector be installed within the same room, you must follow the re-quirements of your local code. Check with your local building department for requirements in your area.

INSTALLATION

FLOOR PROTECTION - Cascade This appliance requires noncombustible floor protection. If the floor protection is to be stone, tile, brick, etc., it must be mortared or grouted to form a continuous non-combustible surface. If a chimney connector extends horizontally over the floor, the protection must cover the floor under the connector and at least 2" to either side. A noncombustible floor protector must fully cover the area beneath the appliance and extend 6” to the front, 6” to the sides, and up to 6" from the back as illustrated be-low.

*Note: When installed at clearances less than 6”, floor pro-tection is only required to extend to the wall.

MANUFACTURED (MOBILE) HOME EXHAUST VENT PIPE INSTALLATION GUIDELINES Use only “PL” pellet vent pipe listed to UL641 and ULC S609..Pipe should extend at least 3 feet above the part of the roof through which it passes. The top of the pipe should be at least 2 feet above the highest required elevation of any part of the manufactured (mobile) home within 10 feet of the pipe (see Manufactured [Mo-bile] Home Chimney Height Requirements, on page 9). If the exhaust vent exits the manufactured (mobile) home at a location other than the roof, and exits at a point 7 feet or less above the ground level on which the manufactured (mobile) home is position a guard or method of enclosing the pipe shall be provided at the point of exit for a height of up to 7 feet. The openings, if any, in this guard shall not allow a 3/4” rod to pass through. A 1/2” rod could pass through but should not be able to touch the pipe when inserted through the opening a distance of 4 inches.

INSTALLATION CHECK LIST It is strongly recommended that you have an authorized Lennox Hearth Products dealer install your stove. If you install your stove yourself, you should review your in-stallation plan with your authorized Lennox Hearth Products dealer. Check list: Check off each item as you proceed with the installation process. Read the ENTIRE stove installation section first. Determine the appropriate measurements and loca-

tions for your installation. Follow the general installation directions under In-

stallation. Be sure to pre-fit all items before you install, fasten,

or set up the stove permanently. Prior to lighting your stove: Review the Important Warnings section (page 2). Review Fuel Specifications (page 17). Review and follow instructions in the Care and Op-

eration Section (pages 14 to 17). Plug power cord connector into corresponding con-

nector on the back of appliance. After you have begun operation of your stove: Review the routine cleaning / maintenance informa-

tion. Enjoy the warmth from your new Lennox Hearth

VENTING REQUIREMENTS It is recommended that only an authorized dealer install your pellet stove. The specified installation requirements must be followed to ensure conformity with both the safety listing of the appliance and local building codes. All clearances, installation instructions and precautions specified by the vent manufacturer must be followed. Selecting a Location - Review the appliance clearance requirements before installing the venting system (see page 5). Position the appliance far enough away from walls to allow adequate room for servicing. Choose the appliance location with the least amount of interference with the house framing, plumbing, wiring, etc. Preferred Vent Configuration – For the best perform-ance, we recommend a vent run design which runs verti-cally and terminates above the roofline. This design will allow natural draft to improve the flow of flue gases and will aid in combustion and stove performance. Type of Pipe - This stove requires type “PL” vent pipe (pellet vent pipe, sometimes referred to as “L-Vent pellet vent”), listed to UL 641 and ULC S609. Connect the pellet vent pipe or the “tee” to the flue collar using a minimum of three screws and seal as specified in “Pipe / Liner Joint Requirements” on this page. Do not use class B gas chim-ney or single wall chimney as a substitute. Size of Pipe -These pellet appliances are approved for use with the following vent sizes: 3” (75mm) standard, or 4” (100mm). See page 10 for determining correct size vent to use. Use a 3” (75mm) to 4” (100mm) adapter (Cat. No. 14M81) or a 3” (75mm) to 4” (100mm) “tee” in order to run 4” (100mm) pipe. Note: If installation requires in excess of 11 feet (3 1/3 meter) of pipe, it is recommended that 4” (100 mm) pipe be used. Offsets - In every installation, a single or double clean-out “tee” is recommended for every ninety-degree offset (this tee will help collect ash residue and will allow for routine cleaning without the need to disconnect sections of pipe). Note: Offsets and horizontal runs accumulate fly ash and soot, which reduces the exhaust flow and performance of the stove. Total Offsets in venting system should not exceed 270° total in direction change.

Horizontal Runs - The maximum total horizontal run must not exceed 10 feet (3.1 meters). Horizontal run of pipe requires 1/4” (7mm) rise per foot. Pipe Clearances / Requirements – See pipe manufac-turers instructions for installation of venting components and clearances. Follow pipe manufacturers installation precautions for passing pipe through a combustible wall or ceiling (i.e. use an approved thimble). Notes: Pellet vent pipe requires 3” (75mm) clearance from out-side of pipe unless otherwise specified by vent manufac-turer - all diameters: 3” (75mm) and 4” (100mm). A support bracket must be installed every 4’ (1.2m) of pellet vent pipe on the exterior wall of the house unless otherwise specified by vent manufacturer. Pipe / Liner Joint Requirements - All pipe joints must be secured with a minimum of 3 screws. ALL horizontal joints must be sealed gas tight. Use RTV silicone with a rating of at least 570° F (969° C), or Interam to provide a complete seal at the flue collar and on all joints. Connection to Masonry Chimney through a Wall - Be sure to verify the construction of a masonry chimney, as it may have combustible framing. The use of single wall flex or rigid 24 gage stainless steel pipe as a liner is approved. Connection to an Existing Class A Chimney - - A chimney adapter can be used to make the connection from 3” (75mm) or 4” (100mm) pellet vent pipe (listed to UL 641 & ULC S609) to existing UL chimney system. Verify with the pipe manufacturer that your pipe brands will interconnect. Horizontal-Vent Installations: On all horizontal-vent installations (short, horizontal runs with no vertical pipe); care should be taken when choosing a location for termi-nating the vent. It is not recommended to directly vent the exhaust on the prevailing wind side of the house. It is recommended that when an appliance is vented directly through a wall, a minimum of 8’ (2.5m) of vertical pipe should be installed to create some natural draft. This will reduce the possibility of smoke or odor entering the dwelling during appliance shutdown or loss of power.

VENT TERMINATION Do not terminate vent in an enclosed or semi-enclosed area such as: carports, garage, attic, crawl space, under a deck, porch, narrow walkway, closely fenced area, or any location that can build up a concentration of fumes such as a stairwell, covered breezeway etc. Vent surfaces can get hot enough to cause burns if touched. Adults should supervise children when they are in the area of a hot stove. Non-combustible shielding or guards may be required. Termination Cap: The termination of the outside chimney of the pellet stove shall be located in accordance with the follow-ing: A. Higher than 3’ (.92m) above any forced air inlet (air con-

ditioner, etc.) located within 10’ (3m). B. Not less than 4’ (1.2m) below, 4’ (1.2m) horizontally from

or 1’ (3.1m) above any gravity air inlet (door, window, etc.) which flue gases could re-enter the dwelling.

C. Not less than 2’ (.6m) from combustible materials such as an adjacent buildings, fences, protruding parts of the structure, roof overhang, plants and shrubs, etc. and not less than 7’ (2.1m) above grade when located adjacent to the public sidewalks (access). The final termination of the exhaust system must be configured so that flue gases do not jeopardize the safety of people passing by, overheat combustible portions of nearby structures or en-ter the dwelling.

D. Not less than 3’ (.92m) below an eave (maximum over-hang of 3’ (.92m) or any construction that projects more than 2” (51mm) from the plane of the wall.

E. The distance from the bottom of termination to grade is 12” (305mm) minimum. This is conditional upon plants and nature of grade surface: Be careful to choose a loca-tion for the vent termination, which does not expose peo-ple or shrubs to high heat from the exhaust gases. The exhaust gases are not hot enough to ignite grass, plants and shrubs located in the vicinity of the termination al-though they should be a minimum of 3’ (.92m) away. The grade surface under the termination must not be a lawn.

F. Since sparks may escape from the exhaust pipe of any stove, use caution when positioning the vent pipe. Refer to pipe manufacturer’s instructions when installing and terminating the exhaust). The vent pipe should be hori-zontal and never run the pipe in a downward direction (recommend a ¼” (7mm) rise per foot horizontal).

Notes: • It is not recommended to terminate exhaust vent on

the prevailing wind side of the house. • It is not recommended using a termination cap with

a screen (fly ash can collect in a screen resulting in blockage).

Site Built Residential Home Chimney Height Requirements The vent termination height required is - USA, 1-foot minimum; Canada 3-feet minimum above the roof pene-tration point as illustrated below (Ref. USA - National Standard, NFPA 211, Clause 7-4.1 and Canada National Standard CSA B365-01, Clause 5.6). Check with your local building official for additional requirements for your area.

Manufactured (Mobile) Home Chimney Height Requirements The chimney must extend 3’ (.92m) above the level of roof penetration and a minimum of 2’ (.61m) higher than any roof surface within 10’ (3m) (see below). Check with your local building officials for additional requirements for your area.

To pass inspection in nearly any jurisdiction, the chimney must meet both safety and exhaust flow requirements. The (3’ by) 2’ by 10’ rule applies to both masonry and factory built chimneys. * Ref. NFPA 211 Clause 7 – 4.1.2, Vents installed with a listed cap shall terminate in accordance with the terms of the cap’s listings.

INSTALLATION

INSTALLING YOUR FREESTANDING PELLET STOVE Standard Horizontal Vent Installation All PL Venting Components must be listed to UL 641 & ULC S609 1. Locate the proper position for the type “PL” wall

thimble. Avoid cutting wall studs when installing your pipe. Use a saber saw or keyhole saw to cut the proper diameter hole through the wall to accom-modate the wall thimble. Use extreme caution to avoid cutting into power lines within the wall of the home. The hole size will depend on the brand of pellet vent that you are using. Install the wall thimble in the hole. ALL INTERLOCKING PIPE CONNECTIONS WITH-IN THE ROOM MUST BE SEALED WITH RTV AND SECURED WITH A MINIMUM OF 3 FASTENERS PER CONNECTION.

2. Position the stove approximately 12” (.3m) from the wall on the floor pad. Push listed type “PL” pipe through wall thimble. Squeeze a bead of high tem-perature silicone (RTV) sealer around the end of the machined portion of the 3” (75mm) pipe connector on the back of the stove. Firmly push on a section of listed type “PL” pipe until inner pipe liner pushes into the bead of RTV sealer.

3. Push the stove (with pipe attached) towards wall. Pipe will go through the wall thimble. Do not position the back of the stove closer than 1” (25mm) from the wall. Note: Greater back clearance will improve the ser-viceability of the stove.

4. Install listed type “PL” 45-degree elbow with rodent screen or cap (optional) on outside end of pipe. The rodent screen should be no less than 1/2” (13mm) mesh and may clog with soot and ash if left unat-tended during the burn season. NOTE: The end of the exhaust pipe must extend a minimum of 12” (.3m) from the outside of the building.

5. If the installation includes a source of outside com-bustion air; cut a separate hole through the wall for the fresh air tube. This tube should be 1-5/8” (42mm) [min.] diameter, steel only. Connect outside air pipe to air inlet on stove. This tube must be terminated with a 90 degree elbow or hood.

NOTE: Combustion air may also be drawn from a vented crawl space under the home. All joints for con-nector pipe are required to be fastened with at least three screws. If vented horizontally, joints shall be made gas-tight in a manner as specified above. Install vent at clearances specified by the vent manufacturer.

INSTALLATION CONFIGURATIONS / STANDARD VENT-ING OPTIONS This appliance may be connected to an existing flue or by installing type “PL” vent pipe (listed to UL 641 & ULC S609). If a liner is run all the way to the top of the exist-ing chimney, the existing flue should be sealed with a steel plate. Start a vertical run with a Tee at the back of the stove. Other options are illustrated below. Note: See Vent Termination Requirements on page 9.

Preferred Installation – Vertical Vent Through the Roof. This venting configuration allows for the best stove performance. The vertical pipe promotes natural draft and with the chimney inside the dwelling, the flue gases stay warm, thus rising at a consistent rate.

CARE AND OPERATION

PAGE 14

Heat Output Switch - The Heat Output switch activates both the convection and combustion blowers and the au-ger motor. If the exhaust does not reach operation tem-perature within 25 minutes, the stove will automatically shut down. If this occurs, repeat the lighting procedure (pre-lighting instructions). “OFF” position - The “Off” position on the Heat Output switch will turn the stove off by turning off the auger mo-tor. The remaining fuel in the grate will safely burn up. Once the stove has cooled sufficiently the blowers will shut off automatically. “HIGH HEAT” position - The “High Heat” position on the Heat Output switch will increase the fuel feed rate and blower speed for maximum heat output.

“LOW HEAT” position - The “Low Heat” position on the Heat Output switch will decrease the fuel feed rate and blower speed. Auger “On” Light - The red L.E.D. light on the control panel indicates when there is power to the auger motor. Under normal operation, this light will blink on and off. Fuel Feed Trim Control - The fuel feed trim control on the control panel should be used when the damper con-trol will not correct a poor combustion problem. Turning the trim control counter clockwise will decrease the amount of fuel entering the UltraGrate and turning the trim control clockwise will increase the amount of fuel entering the UltraGrate. The trim adjustments com-pensate for fuel differences. Factory set “ON” time is 1.9 seconds. The trim range is 1.6 to 4.5 seconds. Fac-tory “OFF” time for low is fixed at 4.2 seconds and for high it is fixed at 2 seconds

♦ Estimated heat input based on fuel value of 8,400 BTU

per lb. of fuel. Note: It is normal for some ash to build up on the inner glass surface at the lower burn settings. INITIAL START-UP / EMPTY HOPPER OR FEED TUBE: During an initial start-up, or in the case where the hopper has run out of fuel, it will be necessary to prime the auger feed system. To prime the auger feed tube: 1. Ensure all packing material and foreign objects are re-

moved from the hopper. Fill the hopper with recom-mended pellet fuel and plug the stove into the wall out-let.

2. Move the Heat Output switch on the control panel to the “HIGH HEAT” position to activate the auger and blow-ers.

3. Look through the combustion chamber door and when you can see the first pellets dropping into the grate, the auger is fully primed. This will take up to 10 minutes.

STARTING YOUR PELLET STOVE 1. After the auger is fully primed, adjust the Heat

Output switch to the “OFF” position. 2. Place a small amount of an approved (non-

volatile) gel fire starter on top of the pellets in the UltraGrate (if chips are used as firestarter, place chips in UltraGrate first then place pellets on top). Consult with your authorized Lennox Hearth Products dealer for approved fire starting prod-ucts). DO NOT USE FLAMMABLE LIQUIDS TO START YOUR STOVE.

3. Light the fire starter in the UltraGrate with a match and close the door.

4. After approximately 10 seconds, move the Heat Output switch on the control panel to the “LOW HEAT” position. You will notice that the fire will become active and there will be air coming from the heat exchanger tubes and pellets will now be-gin to feed into the UltraGrate.

5. After the fire is burning well, adjust the Heat Out-put switch to the desired setting. Adjust the damper control if necessary for proper combus-tion. Look for a brisk, bright yellow to whitish flame.

Remember, different brand fuels feed at different rates. TURNING OFF YOUR STOVE Move the Heat Output switch to the “OFF” position. This will stop the fuel feed and any remaining fuel in the grate will safely burn up. The blowers will con-tinue to run until the stove has cooled off sufficiently and will then shut off automatically.

CARE AND OPERATION

DAMPER OPERATION The damper is a plate that helps control the amount of airflow supplied for combustion. With the damper pushed in all the way, the airflow is at its minimum. As the damper is pulled out, more air is allowed to flow. It is very important to preset your damper prior to burning your pellet stove.

The Damper Control is located on the right side of the stove. The damper should be pushed all the way in toward the stove during initial operation. It may need to be manually adjusted outward depending on the type of pellet fuel being burned. The damper control adjusts the amount of combustion air to the UltraGrate. When the damper has been correctly adjusted, you will observe a brisk, yellow-to-whitish flame. Fuel should not “pile-up” in the grate. The proper air settings will vary from stove to stove due to installation, altitude, and the fuel being burned.

Top View of Stove

DAMPER ADJUSTMENT: It will be necessary to monitor the appearance of the flame during the first 4-8 bags of pellets. If your flame is smoky red / orange with evidence of soot at the top of the flame, you need more combus-tion air; pull the damper out slightly and re-evaluate the appearance of the flame. It may be necessary to con-tinue this process, moving the damper outward incre-mentally until proper combustion is attained (the flame should become yellow and begin to “dance”). If the flame is “short” at the higher burn rates, or if the pellets are burning up in the grate before new pellets are fed into the fire, push the damper slightly inward and monitor the flame. Continue the process of moving the damper incrementally and evaluating the flame until proper flame appearance is achieved.

Once the damper has been properly set it should not need adjusting unless you are changing from a premium grade pellet to a standard or high ash pellet, in which case the damper may need to be pulled out to help pre-vent the accumulation of ash in the grate. DAMPER ADJUSTMENT GUIDELINE Lack of Combustion Air: By opening the damper, this will increase combustion air delivery. Symptoms of insuf-ficient combustion air include; unburned fuel, lazy smoky or red / orange flame, excessive ash or soot, excessive buildup on glass, fuel may “pile-up.“

Contributing factors: • High Altitude – Lack of oxygen • Restrictive Venting (elbows, horizontal runs,

cold external chimneys, etc.). • Dirty / Poor Quality Fuel.

Note: Excessive amounts of fly ash built-up in the grate, clinkers in the grate or leakage of air (if the grate is not properly seated) will starve the fire for air. See Routine Maintenance, on pages 18 and 21 for information on cleaning the stove. Excessive Combustion Air: By closing the damper, this will reduce combustion air delivery. Symptoms of excessive air include; fuel burns too quickly (results in smoking or smoldering pellets or pellets burn up before new pellets are fed), white to yellow flame, etc. If the damper is open too much, the burning pellets will lift off the grate and fly up into the air much like popping corn does. Contributing factor:

• Venting system providing excessive draft. Correct Combustion Air / Proper Burn Characteris-tics: When the damper is correctly set, the burning pel-lets should move (wiggle) around slightly and the flame should be bright yellow and “dance.” Pellet Feed / Pellet Size: The pellet feed system is designed to handle a wide range of pellet sizes up to a maximum of 5/16" diameter. Different pellets may feed at considerably different rates. You may notice a difference in the burn if you change pellet fuel sizes. The longer the pellet, the slower it will feed and vice versa. If the stove will not stay burning at the minimum fuel feed setting, those particular pellets may not be feeding fast enough. If this happens, reduce the amount of combustion air by adjusting the damper (see Damper Adjustment on this page).

CARE AND OPERATION

Long Burn Time: When operated correctly, this appliance cannot be over-fired. Continuous operation at a maximum burn can, however, shorten the life of the electrical components (blowers, motors, and electronic controls), and is not rec-ommended. Typical approved operation would include running at the low setting with occasional running on the maximum setting during the coldest periods of the winter. The lower heat setting is recommended for overnight operation or when the room is vacated for long periods of time. Note: See Fuel Delivery Rate on page 15 for burn times. AUTOMATIC SAFETY FEATURES Power Outage: During a power outage, the stove will shut down safely. It will not automatically restart when the power is restored. However, a momentary power interruption may not shut your stove down. Following a loss of power a small amount of smoke will likely leak from the top of the window glass, the hopper and from the combustion air intake, if the stove is vented horizon-tally. This will not persist for more than 3 to 5 minutes and will not be a safety hazard. Your smoke alarm could go off. To re-light the stove, follow the normal procedure for starting your stove. NOTE: If the area in which you live is prone to frequent power outages, it is recommended that a minimum of 8ft (2.5m) of vertical vent pipe be included in the installation to induce a natural draft in the event of a power outage. Overheating: A high limit disc (thermal switch) will auto-matically shut down the stove if it overheats. The stove will need to be manually re-lit. Allow up to 45 minutes cooling time before re-lighting. If the overheating contin-ues, contact your authorized Lennox Hearth Products dealer for more information. Pellet Fuel Hopper It is recommended to open the hopper lid by grasping it on the side as shown in the following picture.

Open Hopper Lid by Grasping the Front Side Be very careful not to touch other hot areas on stove!

Fuel Specifications: Using the UltraGrate burn sys-tem, this appliance has been designed to burn wood residue pellets with up to 3% ash content. Agricultural pellets (i.e…corn, alfalfa etc.) are not permitted to be burned in the stove. Dirty fuel will adversely affect the performance of the stove. Caution: The use of unapproved, dirty, wet and / or high salt content fuel will void the warranty! Wood pellets manufactured to the Pellet Fuels Institute (P.F.I.) certification standard are available in two grades, standard and premium. The primary difference between the two is the ash content of the pellets. The P.F.I., specification for standard grade & premium grade residential pellet fuel is as follows:

• CHLORIDES (Salt): Less than 300 p.p.m.. • BULK DENSITY: 40 lb. / cu. ft. minimum • MOISTURE CONTENT: 8% maximum • ASH CONTENT: < 3% maximum (standard

grade) < 1% maximum (premium grade) • FINES: 0.5% maximum through a 1/8” screen

Clinkering: Silica (or sand) in the fuel, along with other impurities, can cause clinkering. A clinker is a hard mass of silica formed in the burning process. Clinkering is a function of the fuel, (not the stove), but adversely affects the performance of the stove by blocking off the air pas-sages in the grate. Even P.F.I. approved pellet fuel may tend to clinker. A clinker can be removed from the Ultra-Grate and placed in the ash pan with the use of the grate scraper / ash pan tool furnished with your stove. See Routine Maintenance on pages 18 and 21 for more information on cleaning. Ash: The frequency of removal of the ash and mainte-nance performed on the stove is directly proportional to the ash content of the fuel and the operation duration of your pellet stove. Low ash fuel may allow longer intervals between cleaning, however, a stove burning high ash fuel may need to be cleaned as often as everyday. PLEASE NOTE: Lennox Hearth Products has no control over the manufacturing of pellet fuel and will not be held responsible for poor stove performance or any damage caused by inferior pellet fuels. FUEL FEED RATES Different brands of pel-lets will feed at varying rates due to their size and density (length and diameter). This may re-quire a slight adjustment in the damper adjust-ment (see page 16) or the fuel feed trim control to compensate (see page 14).

Open hopper by grasping the front side, then lift until it hinges back to the full open posi-tion.

UltraGrate

ROUTINE MAINTENANCE * Inspect your stove at minimum frequency stated until you establish a minimum frequency required for your instal-lation (frequency will vary depending upon fuel BTU value / ash content, usage, and misc. installation variables).

ROUTINE CLEANING Note: Stove will need to be shut off and cooled enough to handle before routine cleaning is performed. Always dis-connect power before doing any routine cleaning. The following areas need to be inspected during routine cleaning: • UltraGrate (burn grate) • Ash Slide Plates • Ash Pan • Heat Exchange Tubes • Exhaust Passages and Vent Pipe

Maintenance Reference Diagram

ULTRAGRATE (BURN GRATE) The UltraGrate should be inspected periodically to as-sure that the air holes have not become clogged with ash or clinkers. The UltraGrate can easily be cleaned with the grate scraper / ash pan tool, or it can be removed for cleaning. It is very important to monitor the ash build up under the UltraGrate, as excessive amounts of ash will block combustion air from entering the grate, causing pellets to pile-up in the grate.

ROUTINE MAINTENANCE

ASH SLIDE PLATES Ash that accumulates around the grate can be “dropped” into the ash pan by simply opening the two ash slide plates. The ash slide plates are located under the ash lip of the stove. Using the grate scraper / ash pan tool, grasp each plate and pull it toward you. This will allow the ash to dump or be swept into the ash pan below. Do not operate your stove with the ash slide plates open! This will cause poor combustion and the pellets will pile up in the grate. NOTE: It is recommended to pull the ash slide plates every half ton of fuel burned, this will vary depending on the ash content of the fuel being burned.

Cleaning Firebox with Ash Slide Plates

(Recommended Frequency of 1 day – 2 weeks)

NOTE: Make sure to fully close the plates when finished. Failure to close the ash release slide plates completely may cause the fuel to burn poorly (due to reduced airflow through the grate), which may then cause pellets to “pile up” in the grate. ASH PAN NOTE: Periodically check for ash build up under the Ul-traGrate. If the ash is allowed to build up to the bottom of the UltraGrate, there will be a loss of combustion air and the pellets will start to pile up on the grate.

Proper Disposal of Ashes: NEVER place ashes in a cardboard box or any other combustible receptacle. Ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be placed on a noncombustible floor or on the ground, well away from all combustible materials, pending final dis-posal. If the ashes are disposed of by burial in soil or other wise locally dispersed, they should be retained in the closed container until all cinders have thoroughly cooled.

Emptying Ash Pan

(Recommended Frequency of 2 days – 2 weeks) EXHAUST PASSAGES AND VENT PIPE Inspect frequently and clean when necessary. Fly ash will accumulate at all bends in the exhaust system. Note: Large amounts of fly ash build-up will create a lack of combustion air. Removing the Tee cap on vertical instal-lations will allow an inspection of the ash build-up in the exhaust Tee and will help you to decide how frequently more extensive cleaning must be performed.

ROUTINE MAINTENANCE

HEAT EXCHANGER TUBES ENSURE STOVE IS COLD BEFORE CLEANING HEAT EX-CHANGE TUBES. Remove fly ash from heat exchange tubes as follows: 1. Ensure the door is secured closed. 2. Open the hopper lid (see Pellet Fuel Hopper, page 17). 3. Using the hole in the handle of the grate scraper tool, “grab”

onto the heat exchange rake handle located above the door (in the center).

4. Pull the grate scraper tool back and forth several times (up-ward and forward, then back) to rake a way fly ash from the heat exchange tubes.

Note: If a more thorough cleaning of heat exchange tubes is de-sired, the baffle plate in front of the tubes can be easily removed (slide baffle plate forward until screw heads clear the notches on each side, then remove baffle). With baffle plate removed, use a small brush to clean between tubes (see pages 27 and 30, item #30).

Removing Fly Ash from Heat Exchange Tubes

Recommended Frequency of 2 days – 2 weeks

DOOR ROPE GASKET The condition of the rope gasket around the door and windows should be checked periodically and replaced or repaired if necessary. A strip of pa-per or a paper bill (i.e. one-dollar bill) may be used to perform a test of the integrity of the door seal. Close the door on the paper in several dif-ferent locations and pull. It is normal to feel only a slight amount of friction. The door gasket does not need to be “tight” in all area since a small amount of air drawn into the stove around the gasket is not hazardous or detrimental to the per-formance of you stove.

ROUTINE MAINTENANCE

WINDOW WASH Periodically insert a small piece of cardboard (a business card) between the window trim and the window. Slide the card back & forth a few times to clear any dust or fibers from the window wash gap. Open the door and repeat from the other side of the glass.

Window Wash

(Recommended Frequency of 1 year)

Note: The air wash gap should be approximately .075” to .090.” REAR STOVE COMPARTMENT The rear stove compartment should be cleaned periodi-cally (a minimum of once a year). DISCONNECT ELEC-TRICAL CORD PRIOR TO CLEANING STOVE. Any household dust, pet hair or sawdust should be vacuumed or wiped out of the rear compartment of the stove, room air blower, and combustion blower (paying special atten-tion to vacuuming out the intakes of both blowers). The electrical components should be wiped clean. To access the rear stove compartment, see following illustration and instructions for opening side panels.

MOTOR LUBRICATION The blowers are permanently lubricated by the manufacturer. Do not apply oil to any part of the blower. Doing so may cause damage. SMALL AREA PAINT TOUCH-UP The stove body is painted with a quality high-temperature stove paint. Use only model TSPK-B Stove Paint, Catalog # 70K99. Do not touch-up your stove with any other paint. Using one small piece of 320 grit sand paper and lightly sand the blemish so that the edges are “feathered” or smooth to the touch between the painted and bare sur-faces. Do not let the sand paper gum up with paint, as this will cause scratches on the metal surface. If there are any scratches, use 600 grit sandpaper instead. Mask off surfaces you do not want painted. Paint lightly over the bare surface first as this will act as an undercoat. Then paint over a larger area in smooth even strokes to blend. CONTROL BOARD REMOVAL PROCEDURE UNPLUG STOVE BEFORE FOLLOWING THIS PRO-CEDURE. The electronic control board is located on the left-hand side of the stove. It is mounted to the side panel with four nuts. The control board can be removed or replaced by performing the following procedure. Note: The control cable is fitted with a quick-disconnect plug that snaps into the back of the control board. The blower and motor wires are all part of the stove wiring harness. 1. With the stove unplugged, open the left side panel by

removing the two bolts located on the top and bottom side of the panel. Pull the edge closest to the door firmly away from the stove and swing side panel open.

2. Disconnect the wiring harness from the control board.

3. Locate and remove the four nuts that secure the con-trol board to the side panel of the stove.

4. To re-install your control panel, reverse procedures above.

5. Plug the stove into your wall outlet. (Recommended Frequency – N/A). The electronic

control board is very reliable and should be one of the last components replaced when troubleshooting a stove operational problem.

1.Open Hopper.

2. Turn small knob with fingers until top of panel clears this notch.

4. Swing open hinged panel.

3. Loosen bottom screw until panel clears this notch (1/4"”hex head screw)

5. Unthread damper arm and set aside.

6. Follow #2 through #4 to open right side panel.

DEFINITIONS

Air Wash To inhibit buildup of soot on the door glass, air is deliv-ered to the glass through an air wash system located in the doorframe surrounding the glass. Auger It transfers the fuel down the burner tube into the Ultra-Grate. Auger Motor Motor specifications are: .4 Amp, 1 rpm (revolutions per minute). It drives the auger to deliver fuel to UltraGrate. Blower, Convection (Room Air) The blower’s function is to transfer the heat from the ap-pliance to heat the room air. Specifications: CFM - 66 low, 102 high; RPM – 1350 low, 2200 high; Current Draw – 2.10 Amps. Blower, Combustion (Draft Inducer) The combustion blower has a radial impeller to deliver more air to the UltraGrate. It pulls air into the Ultra-Grate by creating a negative pressure. This is done by extracting the exhaust gases out of the firebox and push-ing the exhaust downstream to the flue exit. Specifica-tions: CFM - 33 low, 56 high; RPM – 1350 low, 2200 high; Current Draw – 2.10 Amps. Disc, Convection High Limit (L190-20F, N / C) If the temperature of the convection air chamber reaches 190° F., the high limit auto reset will “trip” and stop the flow of electricity to the auger motor. It will not automati-cally reset until it has cooled below 170° F).

Disc, Low Limit (F140-10F, N / O) At stove temperatures above 140 F, this disc closes con-tacts and allows power flow to the auger motor UltraGrate (Burn Grate) This is where combustion occurs. Hopper The hopper is where the pellets are stored. Heat Output Switch This is the main power switch, which controls power to the feed system auger motor, combustion blower and convection blower. It has 3 feed rate settings, which con-trols the burn rate. Pressure Switch The pressure switch is a safety device used to shut off the feed system (auger motor) if there is too much back pressure in venting system. Some possible causes are as follows: ♦ The venting system is obstructed. ♦ High altitude or other misc. environmental condi-

tions affecting exhaust flow. ♦ Improper venting system.

TROUBLESHOOTING Qualified Technicians Only Unplug Appliance Before Performing Any Troubleshooting or Maintenance

PROBLEM CAUSE(S) SOLUTIONS 1. Fire burns with

a lazy orange flame. Pellets build up in the grate and the window soots up.

There is insufficient combustion air.

Remove any clinkers or ash from the bottom of the grate that might be obstructing the primary air holes. Change to a better grade of fuel if necessary. Check that the damper has been properly adjusted (see Damper Adjustment Guidelines on page 16). Inspect heat exchange tubes for ash buildup and remove ash if necessary. Clean internal exhaust ducts. Check if door is sealing properly (see “Door Rope Gasket” on page 20 for test procedure). Check for blockage in the air inlet tube or exhaust pipe. Clean as necessary. Close ash slide plates. Have your authorized Lennox Hearth Products dealer check your combustion blower.

2. Fire goes out or stove shuts down automati-cally

The hopper is empty Pellets are not feeding. The high limit disc has tripped. There is too much combustion air for the amount of fuel.

Refill hopper. See pellets will not feed on this page. Allow stove to cool for 1 hour and re-light. If the stove has been operating at a medium to high burn rate and the con-vection (room air) blower has been turned down low then the blower should be turned up higher. If this problem persists (particularly at lower burn rates), then the high limit disc should be replaced by your authorized Lennox Hearth Prod-ucts dealer. Adjust the damper to reduce combustion airflow. (see Damper Adjustment Guidelines on page 16).

3. Pellets will not feed.

Stove has run out of fuel. The auger motor or circuit board may be defective. The pressure switch tap or hose may be blocked. Back pressure in venting tripping pressure switch. High limit disc may have been tripped. Self-aligning bearing in auger motor may be mis-aligned.

Refill hopper. Check to ensure that there is no blockage in the pressure tap or hose. Have your authorized Lennox Hearth Products dealer diagnose the problem and clean or replace any nec-essary parts. If new installation check for excessive 90˚ bends, long hori-zontal runs or excessive vertical run of 3” pipe. Possibly change to 4” pipe. If older installation check for excessive ash accumulation in pipe or other obstructions. Clean out pipe. Allow stove to cool. Gently tap the auger motor.

TROUBLESHOOTING Qualified Technicians Only Unplug Appliance Before Performing Any Troubleshooting or Maintenance

PROBLEM CAUSE(S) SOLUTIONS 4. Blowers will

not operate. There is no power to the stove. There is no power to the control board.

Check that the stove is plugged in to the wall outlet. Check to see if your circuit breaker has tripped. Check the wire connections on the high limit disc and Control board.

5. There is soot or fly ash in the house.

The window is being cleaned when the stove is operating. There is leakage at the joints be-tween the combustion fan, connec-tion or exhaust pipe connections. This will be evidenced by dust on the impeller of the convection fan, and in the heat exchanger area. The vacuum cleaner is leaking.

Turn off stove before cleaning to prevent dispersion of ash and soot into the room. Seal up any leaks in the exhaust system with room tem-perature vulcanizing silicone sealer (RTV). DO NOT use a standard household vacuum or “shop vac” as the filters will leak the fine particles of ash. Clean the stove with an approved ash vacuum ONLY.

6. Stove runs for 25 minutes then shuts down.

The exhaust gases are not up to temperature. The low limit disc is not operating correctly. The wires to the low limit disc are loose or disconnected.

Re-light stove if necessary. Replace the low limit disc. Check the connections between the disc and the wiring harness. Make sure that the connections between the disc and harness terminals are secure.

7.Blowers will not shut off after the fuel has been switched off and the stove has cooled down.

The low limit disc has failed in the closed position.

Replace the low limit disc.

8. Blowers will not operate when the Heat Output switch is moved from the “OFF” position.

There is no power to the blower. Check that the stove is plugged in to the wall outlet. Check to see whether the circuit breaker has tripped. Check the wire connections between the high limit disc and the control board and blower.
